I mostly did this to familiarize myself with the codebase and figured it
doesn't hurt to cover this with tests if more added logic in this area,
despite this logic receiving indirect coverage elsewhere. [Here's my
related
proposal](https://github.com/ghostty-org/ghostty/discussions/10807).
I gave more thought around how to expose some of these config values and
their metadata in the C api to eventually drive a settings UI and was
hoping for feedback before I proceed.
The cleanest path forward feels like annotating config values with
formal metadata around things like: supported platforms, whether or not
a restart is required, presentation metadata like grouping + ordering,
tolerated ranges for values, possible enum values, etc. My intent is
that Swift & other consumers can enumerate potential settings values
with metadata such as to drive the UI from the metadata.

AI Disclosure: I used Codex 5.3 to help me understand how the config
subsystem in zig is exposed to Swift via the C API. Codex wrote these
tests; but we brainstormed on a pragmatic coverage balance and I
understand how the tests work.

> I can see there being space for some kind of new sequence that tells
the terminal that "hey, I want a semantic palette" or something, that is
better adjusted to themes automatically. But, I don't think we should
this by default.
> So my concrete proposal is to eliminate the inversion and bg => fg
ramp and do a more typical dark => light ramp (still taking into account
bg/fg, but keeping 16 black and 231 white). I think this is the only way
we can really make this a default on feature. I think this would address
all the negative reactions we've gotten to it.
This adds a new `palette-harmonious`, disabled by default, which allows
generated light themes to be inverted.
Implements the `output` option for the `scroll-to-bottom` configuration,
which scrolls the viewport to the bottom when new lines are printed.

The space-segment patterns in the path regex (dotted_path_space_segments
and any_path_space_segments) greedily consume text after a space even
when we know that the text is the start of a new independent path (e.g.,
`/tmp/bar` in `/tmp/foo /tmp/bar`).
Fix: Add two negative lookaheads after the space in both patterns:
- `(?!\.{0,2}\/)` → don't match if the next segment starts with `/`,
`./`, or `../`
- `(?!~\/)` → don't match if the next segment starts with `~/`
Fixes#8406
Spatial split navigation now wraps at the edges.
We first attempt the nearest spatial target using the existing slot geometry.
If there is no candidate in the requested direction, we synthesize a wrapped
target by shifting the current slot by one full grid in the opposite
direction and reuse the same nearest-distance logic.
This fake target works because the grid is 1x1, so by moving it a full
grid size in the opposite direction, we effectively wrap around to the
other side of the grid.
Closes#9266.
Big Note: I noticed that this worked properly under `NixOS`, but on my
`Ubuntu` VM it didnt.
The reason is in
[src/build/GhosttyI18n.zig](73a93abf7b/src/build/GhosttyI18n.zig (L24-L31))
because the locale is expected in the `<lang>_<region>` without the
encoding suffix. `<lang>_<region>_<encoding>`
```
// There is no encoding suffix in the LC_MESSAGES path on FreeBSD,
// so we need to remove it from `locale` to have a correct destination string.
// (/usr/local/share/locale/en_AU/LC_MESSAGES)
const target_locale = comptime if (builtin.target.os.tag == .freebsd)
std.mem.trimRight(u8, locale, ".UTF-8")
else
locale;
```
If i force it to always trim the encoding it works, but I am guessing
its there for a reason ,so maybe some of the maintainer can shed some
light in the best way forward, as I am not an expert in how other
systems deal with it. Here you see `Open in Ghostty` -> Abrir con

- I wanted to format the `py` file with `ruff` but didnt want to drown
the changes, so maybe something that could be worth doing so that also
our `py` files have std formatting.

This changes the way Ghostty assigns itself and subprocesses to
cgroups and how resource controls are applied.
* Ghostty itself no longer modifies it's own cgroup or moves itself
to a transient scope. To modify the main Ghostty process' resource
controls ensure that you're launching Ghostty with a systemd unit and
use the standard systemd methods for overriding and applying changes
to systemd units.
* If configured (on by default), the process used to run your command
will be moved to a transient systemd scope after it is forked from
Ghostty but before the user's command is executed. Resource controls
will be applied to the transient scope at this time. Changes to
the `linux-cgroup*` configuration entries will not alter existing
commands. If changes are made to the `linux-cgroup*` configuration
entries commands will need to be relaunched. Resource limits can also
be modified after launch outside of Ghostty using systemd tooling. The
transient scope name can be shown by running `systemctl --user whoami`
in a shell running inside Ghostty.
Fixes#2084.

This fixes the issue where our palette generation was changing our
default palette. The default palette is based on some well known values
chosen from various terminals and it was a bit jarring to have it
change.
We now only auto-generate the palette if the user has customized at
least one entry.

We continue to support bash 3.2 for compatibility with /bin/bash on
macOS. `mapfile` was introduced in bash 4.0, so this change introduces a
`read -r`-based helper function for populating COMPREPLY from a list of

## Summary
Remove the hardcoded opaque background (alpha=255) from IME preedit
cells so they respect `background-opacity` like all other cells.
When `background-opacity` is less than 1, preedit (composition) text was
rendered with a fully opaque background, causing the text to appear
highlighted and hard to read. This change removes the explicit per-cell
background from `addPreeditCell`, letting preedit cells fall through to
the global background. The underline indicator is preserved to mark the
preedit region.

`background-opacity` が 1
未満のとき、IME入力中(preedit)のセルが完全不透明な背景で描画され、ハイライトされたように見えて読みづらくなる問題を修正しました。
`addPreeditCell` のセル背景描画を削除し、グローバル背景に委ねることで通常セルと同じ透過表示になります。
preedit領域のアンダーラインは維持されます。
## Test plan
- Set `background-opacity` to a value less than 1 (e.g. 0.5)
- Type Japanese (or other IME input) to trigger preedit
- Verify preedit text no longer appears highlighted
- Verify the underline indicator is still drawn under preedit text
AI disclosure: I used Claude Code to investigate the source code and
generate code changes in this PR.
Fixes#10424
Replaces #10431
The issue is that when the row where preedit was wasn't dirty, we were
layering more preedit cells (identical ones) on top, so it'd appear to
get "thicker".
Closes#9880.

## If you feel like reading more:
- I feel there is a lot of duplication now with the `prompt surface
title` functionality. For the dialog creation, i basically copied-pasted
the `surface_title_dialog`, and some of the `titleOverride` and the
`TabDialogSet` functionality is identical to that of the
`prompt_surface_title`
- I would think about abstracting it out, but first I think Id be nice
to think what the maintainers think about this approach before doing
anything else.

The `cursor` shell feature always used a blinking bar (beam), often to
the surprise of users who set `cursor-style-blink = false`.
This change extends our GHOSTTY_SHELL_FEATURES format to include either
`cursor:blink` (default) or `cursor:steady` based on cursor-style-blink
when the `cursor` feature is enabled, and all shell integrations have
been updated to use that additional information to choose the DECSCUSR
cursor value (5=blinking bar, 6=steady bar).
I also considered passing a DECSCUSR value in GHOSTTY_SHELL_FEATURES
(e.g. `cursor:5`). This mostly worked well, but zsh also needs the blink
state on its own for its block cursor. We also don't support any other
shell feature cursor configurability (e.g. the shape), so this was an
over generalization.
This does change the behavior for users who like the blinking bar in the
shell but have `cursor-blink-style = false` for other reasons. We could
provide additional `cursor` shell feature configurability (e.g.
`cursor:blink` in `shell-integration-features`), but I'll propose that
as its own change.

**AI Disclosure:** I did a lot of rubber ducking with Claude Code while
trying out various ideas. It was particularly useful for this kind of
feature because I could try out one thing and have it evaluate the
impact on all of the shell integration scripts at once.
